With Hurricane Isaac finally in the rear-view mirror, and work crews hit the streets of New Orleans at dawn to clear debris, restore power, fix traffic signals and set up shelters and supply depots for residents who stayed and those coming back. But more than 149,000 customers remain without power. Dozens of streets are still inundated or blocked by heavy tree limbs. Drivers are blowing through intersections with downed traffic signals. As much as 15 inches of rain fell in some places. And power lines are still down.

Mayor Mitch Landrieu cautioned Thursday that much of the city is still a dangerous landscape and urged residents to stay inside as much as possible.

"The game is not over until the game is over, and a lot of stuff can still happen," he said.

Communities in the Venetian Isles, Lake Catherine and Fort Pike areas took the worst of Isaac's brunt, Landrieu said. The Federal Emergency Management Agency made an emergency declaration for Orleans and 34 other parishes to help with debris removal and shelters.

Charles Rice Jr., CEO of Entergy New Orleans, said 1,100 employees working 16-hour shifts will be deployed by the end of the day, focusing first on the city's hospitals before fanning out into neighborhoods with the broadest power outages.

City Health Commissioner Dr. Karen DeSalvo said the city's 14 dialysis centers will open today. Patients are advised to call their own centers for information, but if they can't get through they can call 800.472.8664. DeSalvo also said the city is setting up a shelter this afternoon specifically for patients whose treatments rely on electricity. Those people can call 504.658.2500.

While streetcar and bus service remains closed today as crews clear routes, DeSalvo said the Regional Transit Authority will provide transportation for those with medical needs.

Louis Armstrong International Airport took some damage to its terminal's roof and to a runway. Power is out, Aviation Director Iftikhar Ahmad said. Whether flights begin again will be up to individual airlines, but Ahmad said he hopes those will start as soon as Friday.

More than 2,900 law enforcement, National Guard and emergency personnel remain in action, Landrieu said. City firefighters extinguished three more one-alarm fires last night and this morning, including another lit from a candle, Fire Superintendent Charles Parent said. At least eight blazes have been put out since Isaac zeroed in on southeastern Louisiana Monday.

Police Chief Ronal Serpas said officers responded to 16 incidents of alleged looting, leading to 33 arrests during Isaac's stay above the city. He also said three people were arrested and another three were issued summonses last night for violating the dusk-to-dawn curfew. Landrieu said it will stay in place, and only lifted as soon as it's safe to do so. He didn't give an estimated timeframe.

The city's hospitals are open and accepting patients. Tulane Hospital's emergency room shut down during the storm, but Landrieu spokesman Ryan Berni said it's now accepting walk-in patients.

Crews spent the night trying to assess just how big a job clearing debris from city streets will be. Deputy Mayor of Operations Michelle Thomas said more than 250 employees from the Parks and Parkways Department had been deployed to begin cleaning up.

Curbside solid waste collection will begin Friday, she said.

Grocers, gas stations and hardware stores have begun opening their doors today. All Rouses Supermarkets are open, as are the Whole Foods store on Magazine Street, the two Langenstein's and Robert Fresh Markets. Walgreen's has opened a few locations with plans to bring all 81 stores in the area online soon. Winn Dixie and Walmart have not opened yet, said Aimee Quirk, Landrieu's economic development adviser.

In a sign that the less urgent needs of New Orleanians will soon be addressed, Southern Decadence festival will happen this weekend, Landrieu said.

Also, Tulane University announced that its home game season opener against Rutgers University will go on Saturday as planned. Landrieu also said he was working with the Saints to get them back to the city.

"I had spoken to the Saints last night and this morning and they said they will win the game tonight," Landrieu said. "So I'ma hold you to that."
